Patented May 29, 1951 UNITED STATES PATENT OFFICE APPLYING WAFERS THAMBURGER PATTIES 2 Claims.

This invention pertains to the manufacture of hamburger patties, withparticular reference to the placing of a wafer of paper or othermaterial on each patty as it is moved from the pattyforming machine.

Further and other objects and advantages will be apparent from thespecication and claims, and from the accompanying drawings whichillustrate what is now considered the preferred embodiment of theinvention.

In the drawings:

Fig. 1 is a sectional View of a holder containing a stack of wafers,with a patty moving to the right and about to make contact with thelowermost wafer of the stack;

Fig. 2 is a sectional view on line 2-2 of Fig. l;

Fig. 3 is a plan view of line 3-3 of Fig. 2;

Fig. 4 is a View of the lower part of Fig. l after the patty has beenmoved to the right and has separated the lowermost wafer of the pack,which is falling into position on the patty; and

Fig. 5 shows a portion of a wafer, illustrating the means for holding itimpositively in position in the pack.

Wafers I0 are stacked in a trough-like vertical container having sidesI2 and rear surface I4, and are impositively held in position by avertical rod I6 fast in the table I8 of the machine.

Stud 20 projecting horizontally from one side I2 of the container passesthrough a horizontal hole in a block 22, and a screw 24 clamps the blockin adjusted position on the stud, While block 22 is held in any desiredposition vertically or rotatively by a screw 26.

Mounted vertically Within the container, and close to rear wall I4 is arod 28 which at its lower end is bent around the bottom end of containerwall I4 and welded at 30 to the rear of wall I4.

Wafers I0 have slotted holes 32 at their rear edges (Fig. 5) and thewafers are stacked in the container with rod 28 threaded through holes32. The holes are of such size and shape with reference to rod 28 as toprovide an impositive lock so that a slight pull on a wafer is suicientto detach it from the rod.

The wafers are additionally supported in the container by a pair ofhorns 34 projecting downwardly and inwardly from the lower front cornersof container walls I2.

Resting on top of the stack of wafers is a curved sheet metal weight I8having a hole 38 through which passes vertical rod 28.

As a result of the above method of support the wafers take the droopingposition shown in the drawings with the front bottom edge of thelowermost wafer in the path of the advancing upper corner of each patty40 moving from left to right on conveyor belt 42, as in Fig. 1.

Due to the characteristic stickiness of hamburger, it has been foundthat the adhesion between the patty and wafer is sufficient to overcomethe resistance of impositive lock 32 and the friction between thewafers, the result being that, as disclosed in Fig. 4, the lowermostwafer 44 is drawn from the pack, then falls onto the top of patty 40,and remains there, as indicated by the broken line.

It is to be understood that the invention is not limited to the specificembodiment herein illustrated and described but may be used in otherways without departure from its spirit as defined by the followingclaims.

What is claimed is:

l. In a device for depositing a Wafer into contact with a sticky meatpatty, means for impositively supporting a wafer in inclined position,wafer curving means operative to curve a wafer upwardly towards itssides in order that the initial contact of a moving patty may be againstthe middle portion of the lowermost portion of the wafer, a curved plateadapted to rest on the wafer for insuring the desired curvature of thewafer, and means for moving a meat patty underneath the wafer and intocontact with the under surface thereof whereby said wafer adheres to thepatty and is drawn from its impositive support and falls to a positionof rest on the patty.

2. In a device for depositing a wafer into contact with a sticky meatpatty, means for impositively supporting a Wafer in inclined positioncomprising a vertical rod having a bight under the high side of thewafer, Wafer curving means comprising a horn under each side of thewafer operative to curve a wafer upwardly towards its sides in orderthat the initial contact of a moving patty may be against the middleportion of the lowermost edge of the wafer, and means for moving a meatpatty underneath the wafer and into contact with the under surfacethereof whereby said wafer adheres to the patty and is drawn from itsimpositive support and falls to a position of rest on the patty.
